Still not that quiet, but better

Comments On Sep 05, 2013:I bought the Core 4 and ran it for a short while, but the sound made my ears ring so I bought the quiet insert. It made it quieter, but not as quiet as I was hoping for. It's cheap though and worth the price. I the power didn't seem to change much, maybe just slightly softer on the bottom.
